Violent and well-done tale of hobos riding the rails during the Depression has Marvin as A#1, a legendary hobo who can get on any train, and his protege Cigaret (Carradine), trying to catch a ride on the train of sadistic conductor Shack (Borgnine), who's been known to kill to keep the hobos away. Tense and gritty, with the usual tight direction of Aldridge, beautiful cinematography, and a gripping screenplay. Borgnine is exceptional among a very strong cast.
